Application fil d December 1e, 1904. Serial No. 237,181.

To all whom it may concern:

Be it known that I, WILLIAM H. BATES, a citizen of the United States, residing at Battlecreek, in the county of Calhoun and State of Michigan, have invented certain new and useful Improvements in Spring-Attaching Loop- Ties; and I hereby declare the following tobe a full, clear, and exact description thereof, such as will enable others skilledin the art to whichit appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters marked thereon as points of reference.

This invention relates to attachments for securing springs to supporting-wires, and particularly has reference to that class of fastenings for securing the upper coil of conical spiral springs to the edge binding-wire emgloyed in the construction of cushions,couches,

Much trouble has heretofore been experienced in the construction of spring-cushions to secure the encompassing spring edge wire' to the upper coils of the outer springs, so that the curve of the coil and the edge wire would present an even surface along the edge.

My invention has for its object to overcome this objection and also to provide an article for the purpose, that the same may be easily and quickly united, firm in its fastening, simple in construction, free from abrupt or sharp points, and economical to manufacture.

With these objects in view my invention will be hereinafter more particularly set forth in the subjoined specification and pointed out in the claims.

In the drawings forming a part of this specification, Figure 1 represents a plan View of a convolute spiral spring and the section of an edge binding-wire secured together with my improved loop-tie. Fig. 2 is a front side elevation of Fig. 1. Fig. 3 is an enlarged detail rear view of Fig. 2. Fig. 4 is an enlarged detail end elevation. Fig. 5 is an elevation of the tie-loop, rear view. Fig. 6 is an end elevation, and Fig. 7 is a perspective View.

Inthe drawings, A represents an ordinary convolute spiral wire spring such as is employed in the construction of carriage, car, chair, and couch cushions, and B a wire such as is used to connect the upper coils of a series of springs for forming the spring edge or encompassing band about the top of a cushion preparatory to padding the same for a cover. C represents my improved spring-attaching loop-tie. This tie is formed from a piece of wire having its ends bent to form hooks a 04. These hooks are thence bent'in the same direction at right angles at b b, and the wire is again curved upon itself and forms double 6 loops 0 0, the hooks terminating at right an-v gles to the loops and their points extending above and slightly over the connecting portion d, as shown in Fig. 7. i L

In attaching the encompassing or spring 5 edge wire B to the upper coil of a series of springs A the coil of a spring is first introduced within the tie C by passing the same within the loops 0 0 from the side opposite to the hook ends a. The spring edge wire B is 7 next introduced and is passed within the hooks a over the connecting portion (2 of the tieloop, and the hook ends are bent downward, as in Figs. 3 and 4., and made. to impinge the 1 spring edge wire B and theconnecting portion D, thus preventing the several parts from becoming disengaged. It will be apparent that spring-supporting wires could be attached to springs in a likemanner, the only difference being that the lower coil to a spring would rest at opposite sides and be secured to double parallel wires passing beneath the same.

In securing the spring edge wire B at the extremity of the curve of a spring A the edge of a cushion-covering will not rub and wear 5. through, as is commonly the case where the fastening is made within the curve of the spiral coil.

Having described my invention, what I claim as new, and desire to secure by Letters 9 Patent, is-

1. The combination with a coiledspring and a wire crossing the same, of a wire bent to form double loops and double hooks, the former adapted to receive a coil of the spring, the latter the crossing wire and the coil of the spring, the points of the hooks adapted to impinge the crossing wire and the connection between the loops and secure the several parts intagt, substantially as and for the purpose set fort 2. The combination with a conical, convolute spring and a wire crossing the same near the periphery of an arc of its extremity, of a wire bent to form double, oppositely-disposed 5 loops terminating in right-angular parallel double hooks, the loops adapted to receive the arc of a spring, the hooks adapted to receive the same arc of the spring and the crossing wire, the ends of the hooks adapted to be bent I I0 to impinge the crossing wire and the connecspace formed between the loops, the crossing tion between the loops, substantially as set wire engaging the hooks at the extremity of forth. the spring and back of the connection between 3. The combination with a conical, convosaid loops, the tips of the hooks being bent to 5 lute spring and a wire crossing the same at its impinge the assemblages of parts intact, sub- 5 extremity along the periphery thereof, of a stantially as and for the purpose set forth.
